Does anyone know how much it would have cost to buy a new Speedmaster 145.022 861cal in 1986 from a UK dealer.

Many Thanks

 

Don't really know what the UK RRP was in the mid-'80s, but for what it's worth, this 1983 145.022 (Sold brand new in 1985) for $400.00.
RRP was $695.00
I don't believe the UK prices were that far off.
